With effective checklists, we can be more productive because we are already aware on what to do next as well as the number of pending tasks (forgetting what to do next is a waste of time).

Here’s the thing about checklists–they change all the time. One day’s tasks will differ from the next day’s. One holiday’s packing list will differ from the next. But that doesn’t mean that you’ll need to design from scratch over and over again. Once you’ve perfect one design to suit your style exactly, you can use it as a template for future checklists.
